## External-review route

**State-run process.** Wyoming runs its own external review process meeting the federal standards, so an independent review there is handled through the state program rather than the federal one. This route is the one for insured plans, Marketplace, individual, and employer plans where an insurance company carries the risk. If your coverage is through a job and the employer pays the claims itself (a self-funded or self-insured plan, which is 63% of covered workers), the state process does not apply to you whatever your state operates, and your external review goes through the federal process instead. Your denial letter names your route; if it does not, ask your plan in writing whether the plan is self-funded.

Insurance got denied, what to do next?

We hear this most. [r/HealthInsurance, thread title](https://www.reddit.com/r/HealthInsurance/comments/1rdxwvi/insurance_got_denied_what_to_do_next/) , read September 3, 2026.

The number nobody else publishes, and here it is missing. CMS publishes no external-review figure for Blue Cross Blue Shield of Wyoming in Wyoming, so nobody, including the regulator, can say whether anyone ever got that far. We print no number rather than reading an absence as a zero. Nationally, 4,918 of 83,907,852 denials reached that stage, one in every 17,061, and 22.2% (1,092 of 4,918; interval 22.2-23.8% for counts CMS withheld; 32.6% without SelectHealth) of those were overturned.

Those 333,000 denials are 94.4% of every in-network denial recorded in Wyoming in this release, which makes Blue Cross Blue Shield of Wyoming the 1st largest source of denials of the 2 insurers reporting there. Spread across its 14 plans in the state that is about 23,786 denials per plan. 415 internal appeals were filed against those 333,000 denials. Every one of those denials carried the same two dates the tool at the top of this page works out.

The clock your letter has to describe, in actual dates

Two dates matter more than anything else on this page, and they run the same in Wyoming as everywhere else. You have 180 days from the date on your denial notice to file the internal appeal, and then 4 months from the final internal denial to ask for an independent external review. If waiting would seriously jeopardize your health you can ask for both to be expedited, decided in about 72 hours . Both timeframes are federal, not your insurer's choice, [29 CFR 2560.503-1](https://www.ecfr.gov/current/title-29/section-2560.503-1) ( [PDF](https://www.govinfo.gov/content/pkg/CFR-2024-title29-vol9/pdf/CFR-2024-title29-vol9-sec2560-503-1.pdf) ) and [45 CFR 147.136](https://www.ecfr.gov/current/title-45/section-147.136) ( [PDF](https://www.govinfo.gov/content/pkg/CFR-2024-title45-vol2/pdf/CFR-2024-title45-vol2-sec147-136.pdf) ), in plain English at [HealthCare.gov](https://www.healthcare.gov/appeal-insurance-company-decision/internal-appeals/) , and your own denial letter states the ones that govern your plan. The PDFs are the same sections on govinfo.gov, which serves them without a challenge page, so an automated reader can check these two dates as easily as you can.

Data verified November 4, 2026 · CMS Transparency in Coverage Public Use File (PY2027 release, PY2025 claims), data.healthcare.gov — US Government public domain

You are not alone, and here is the measured version of that sentence: 333,000 in-network claims were denied by Blue Cross Blue Shield of Wyoming in Wyoming in a single plan year. A denial rate is a fact about an insurer's book of business. It is not a judgment about you, and it is not the last word on your claim.

- Of the 2 insurers reporting a denial rate in Wyoming, Blue Cross Blue Shield of Wyoming is the first highest at 20.4%. The highest in the state is 20.4% and the lowest is 17.5%.

- That is 4.7 percentage points above the 15.7% national average across this dataset, and 0.2 points above the Wyoming average of 20.2%.

- Behind the percentage: 1,633,878 in-network claims were processed under 14 plans in Wyoming, and 333,000 of them came back denied.

- For every 10,000 claims Blue Cross Blue Shield of Wyoming denied, about 12 came back as an internal appeal. The other 9,988 stopped at the letter.

- Of the internal appeals it did receive, Blue Cross Blue Shield of Wyoming overturned 20.24% , 84 claims that started life as a no.

- Its most-recorded denial reason is administrative reason at 53.8% of its categorized denials, against 17.2% nationally, a heavier share than the country as a whole. That is the denial mix, not an outcome rate.

- Blue Cross Blue Shield of Wyoming accounts for 94.4% of every in-network claim denied in Wyoming in this file.

- By raw volume it is the 48th largest source of denials among the 135 insurer-state records in the file that report one.

- After that, its second-most-recorded reason is [service excluded from the plan](/denial-reasons/service-excluded) , 80,918 claims, 20.1% of its categorized denials.

- Third on its own list is [member not covered](/denial-reasons/member-not-covered) , 46,077 claims, 11.4% of what Blue Cross Blue Shield of Wyoming categorized in Wyoming. Between them the top three account for 85.3% of its categorized denials.

- Where Blue Cross Blue Shield of Wyoming differs most from the national mix is [administrative reason](/denial-reasons/administrative) : 53.8% of its categorized denials in Wyoming against 17.2% across the file.

- Read the other way round: 1,300,878 of those 1,633,878 in-network claims were paid, 79.6% of everything Blue Cross Blue Shield of Wyoming processed in Wyoming.

- Spread across the 14 plans it reports in Wyoming, that is about 23,786 denied claims per plan, on about 116,706 claims processed per plan.

- Its reason columns add up to 403,135 categorized rows against 333,000 denials, 121.1% of them, and every reason share on this page is a share of that first figure rather than of the second.

- Its smallest recorded category in Wyoming is [provider out of network](/denial-reasons/out-of-network) , 261 claims, 0.1% of what Blue Cross Blue Shield of Wyoming categorized there.

- Against the file as a whole, this one record is 0.4% of the 83,907,852 in-network claim denials reported by every issuer in it.

What to do tonight

- Find the reason code on your denial letter. The reason Blue Cross Blue Shield of Wyoming records most often in Wyoming is administrative reason , but yours may be one of the other 8, copy the exact wording and code off your own letter tonight, because that sentence is what your appeal has to answer.

- Ask Blue Cross Blue Shield of Wyoming in Wyoming for the clinical criteria they judged you against. Under [29 CFR 2560.503-1](https://www.ecfr.gov/current/title-29/section-2560.503-1) they have to hand you the claim file and the policy they applied, free, on request, and you cannot argue with a checklist you have never read.

- Put both deadlines on your calendar before you go to bed. 180 days from the date on the letter for the internal appeal, 4 months from the final internal denial for external review. The free calculator on this page turns your date into the two calendar dates in about ten seconds. Blue Cross Blue Shield of Wyoming overturned 20.24% of the internal appeals it did receive, 84 claims, so the stage you are about to start is not decorative.

None of those three steps costs anything. Anyone charging you to do them is selling you something you can do yourself in twenty minutes.

Blue Cross Blue Shield of Wyoming denies 4.7 percentage points more of its in-network claims than the national average across this dataset.

## What happened to appeals

| Stage | Filed | Overturned |
| --- | --- | --- |
| Internal appeal (to Blue Cross Blue Shield of Wyoming) | 415 | 20.24% |
| External review (independent) | not reported | not reported |

Read the table for what it is: the external-review row above shows a dash, which means not reported and not zero, the Wyoming absence this page states once at the top for Blue Cross Blue Shield of Wyoming and sources once at the foot. External review is free to you and the insurer must follow the decision, whatever this file does or does not record about it.

What that record means for your own Blue Cross Blue Shield of Wyoming letter, and by when. Blue Cross Blue Shield of Wyoming overturned 20.24% of the 415 internal appeals its Wyoming members filed against 333,000 denials, and the Wyoming escalation count for Blue Cross Blue Shield of Wyoming is the figure this page names as absent at the top, so how many of those denials went on to the independent stage is not something this page can tell you, Blue Cross Blue Shield of Wyoming's own rows in the plan-year 2027 release of the CMS Transparency in Coverage file, read November 4, 2026 ( [data.healthcare.gov](https://data.healthcare.gov/) ). Whichever way that lands, nobody files the appeal for you, and the filing runs on a clock set by which plan you hold: an employer or Marketplace plan gives you at least 180 days from the denial notice to file the internal appeal ( [29 CFR 2560.503-1(h)(3)(i)](https://www.govinfo.gov/content/pkg/CFR-2024-title29-vol9/pdf/CFR-2024-title29-vol9-sec2560-503-1.pdf) , carried onto individual-market coverage by [45 CFR 147.136(b)(3)(i)](https://www.govinfo.gov/content/pkg/CFR-2024-title45-vol2/pdf/CFR-2024-title45-vol2-sec147-136.pdf) ), while Medicare Advantage gives you 65 calendar days from the date of its notice ( [CMS](https://www.cms.gov/medicare/appeals-grievances/managed-care/reconsideration-advantage-health-plan-part-c) , [42 CFR 422.582(b)](https://www.ecfr.gov/current/title-42/section-422.582) ) and Medicaid managed care 60 calendar days from the date on the notice ( [42 CFR 438.402(c)(2)(ii)](https://www.ecfr.gov/current/title-42/section-438.402) ), both stages free, and the three steps above are the whole of what to do tonight, so take the date printed on your Blue Cross Blue Shield of Wyoming notice and file well inside whichever of those windows is yours. The free steps are above; the [$29 kit](/appeal-kit) is the same clock with the letters pre-filled for Blue Cross Blue Shield of Wyoming in Wyoming. One payment. No subscription. No cut of your claim.

## Blue Cross Blue Shield of Wyoming inside Wyoming

Your denial did not happen in a national average. It happened in a state market, alongside 1 other insurer reporting into the same federal file, and these are that market's own figures.

- Across the whole of Wyoming, the 2 insurers reporting in this file processed 1,747,592 in-network claims and denied 352,901 of them, a state denial rate of 20.2%. Blue Cross Blue Shield of Wyoming is one of those 2.

- That puts Wyoming fourth of 29 states by denial rate, 4.5 points above the 15.7% national average, before you get to what Blue Cross Blue Shield of Wyoming did inside it.

- Wyoming recorded 485 internal appeals against those denials: one appeal for every 728 claims the state's insurers refused. Blue Cross Blue Shield of Wyoming's own ratio is one for every 802.

- Not one denial in Wyoming reached independent external review in the reported year, not Blue Cross Blue Shield of Wyoming's and not any other insurer's in the state. That is the stage whose decision the plan is required by law to accept.

- The reason Wyoming's insurers record most often is [administrative reason](/denial-reasons/administrative) , 220,606 claims, 50.9% of the state's categorized denials. Blue Cross Blue Shield of Wyoming records the same one most often, so your letter is likely to say it too.

- The other insurers a Wyoming reader could have bought from run from 17.5% ( [UnitedHealthcare Insurance Company](/insurers/unitedhealthcare-insurance-company--wy) ) to 17.5% ( [UnitedHealthcare Insurance Company](/insurers/unitedhealthcare-insurance-company--wy) ). Blue Cross Blue Shield of Wyoming at 20.4% sits above all of them.

- Put the two together and Blue Cross Blue Shield of Wyoming is responsible for 94.4% of every in-network claim denied in Wyoming in this release, from 93.5% of the claims the state's insurers processed.

- Every Wyoming figure in this section is that state's own row in the same federal file Blue Cross Blue Shield of Wyoming's numbers above come from, [CMS Transparency in Coverage Public Use File (PY2027 release, PY2025 claims), data.healthcare.gov — US Government public domain](https://data.healthcare.gov/) , and the full Wyoming page is free at [/states/wyoming](/states/wyoming) .

## What Blue Cross Blue Shield of Wyoming denies most

The most common denial reason recorded for Blue Cross Blue Shield of Wyoming plans in Wyoming is administrative reason . [How that denial is beaten →](/denial-reasons/administrative)

| Denial reason | Claims | Share | National share |
| --- | --- | --- | --- |
| Administrative reason | 217,021 | 53.8% | 17.2% |
| Service excluded from the plan | 80,918 | 20.1% | 13.4% |

| Not medically necessary | 2,364 | 0.6% | 5.5% |

Where these numbers come from The Blue Cross Blue Shield of Wyoming figures on this page, the 20.4% denial rate, the 333,000 denials, are this issuer’s own reported rows in that file. CMS did not report an external-review figure for Blue Cross Blue Shield of Wyoming in Wyoming in the plan-year 2027 release of the Transparency in Coverage file, which is why no external-review count appears above.

Counts: [CMS Transparency in Coverage Public Use File (PY2027 release, PY2025 claims), data.healthcare.gov — US Government public domain](https://data.healthcare.gov/) .

## The pages that answer the next question

- [Every insurer reporting in Wyoming](/states/wyoming) , the state's own row, the 2 companies filing there, and the Wyoming insurance department's consumer number, read at source.

- [Blue Cross Blue Shield denial rate](/company/blue-cross-blue-shield) , Blue Cross Blue Shield of Wyoming is the Wyoming one; the brand's national rate is 18.1% across 191,709,742 claims in 25 states, and it is not the same in any two of them.

- [BlueCross BlueShield of Tennessee in Tennessee](/insurers/bluecross-blueshield-of-tennessee--tn) , 23.5% of in-network claims denied, 1,719,613 of them, the neighboring record in this file.

- [Boston Medical Center Health Plan, Inc. in New Hampshire](/insurers/boston-medical-center-health-plan-inc--nh) , 14.5% of in-network claims denied, 3,681 of them, the neighboring record in this file.

- [BridgeSpan Health Company in Utah](/insurers/bridgespan-health-company--ut) , 20% of in-network claims denied, 1,182 of them, the neighboring record in this file.

- [If your employer pays the claims itself](/self-funded-denial) , then Blue Cross Blue Shield of Wyoming is only administering the plan, your state's external review has no power over the denial, and the route is federal. It is the first question our own calculator asks. 2 insurers report in Wyoming; whether your plan is one of theirs at all is what that page settles.

- [If it was refused before the treatment](/prior-authorization-denied) , a prior-authorization refusal from Blue Cross Blue Shield of Wyoming runs on the same two federal clocks as a denied claim, and it can be appealed while the treatment is still ahead of you. 352,901 in-network claims were denied in Wyoming in this release; a refusal before the treatment is not counted among them and is appealed the same way.

- [Before you pay a lawyer](/before-you-call-a-lawyer) , two free appeals run before anyone bills you by the hour, and Blue Cross Blue Shield of Wyoming has to hand you the claim file for nothing under 29 CFR 2560.503-1. Free help in Wyoming starts with the state consumer line printed on that state's page.

Your dates are ready. [Write the letter, free](/appeal-letter)

## The two federal clocks

The clock your letter has to describe, in actual dates Whatever else is on the page, these two dates are the page. You have 180 days from the date on your denial notice to file the internal appeal, and then 4 months from the final internal denial to ask for an independent external review. If waiting would seriously jeopardize your health you can ask for both to be expedited, decided in about 72 hours . Both timeframes are federal, not your insurer's choice, 29 CFR 2560.503-1 ( PDF ) and 45 CFR 147.136 ( PDF ), in plain English at HealthCare.gov , and your own denial letter states the ones that govern your plan. The PDFs are the same sections on govinfo.gov, which serves them without a challenge page, so an automated reader can check these two dates as easily as you can.

## How rare the second appeal is

You are not alone, measured rather than said: 83,907,852 in-network claims were denied in a single plan year, and only 4,918 of them, one in 17,061, ever reached the independent review stage. Of the ones that did, 22.2% (1,092 of 4,918; interval 22.2-23.8% for counts CMS withheld; 32.6% without SelectHealth) were overturned.

## What is free here, and what the one paid thing costs

Denied a claim? Insurers upheld 165,863 of the 262,982 internal appeals counted in 2024, 63.1% ( KFF ). The win is at independent external review, and the only way to arrive there is to run the internal stage on time, in the right order, with the record intact. That sequence is what the Appeal Kit is.

## What we will not pretend

What we will not pretend. We cannot overturn your denial. Only your plan, or an independent reviewer, can do that. We cannot make your plan cover a service it genuinely excludes. We cannot guarantee external review applies to your denial. It covers medical judgment, experimental or investigational determinations, and rescission, a purely administrative denial may not qualify, and we say so on those pages rather than selling you past it. We have no customer testimonials and publish none. Our evidence is the federal dataset and the regulation cites, both of which you can check.

## Which release these figures are

Which release these figures are Every number on this page is the plan-year 2027 Transparency in Coverage file, issued October 22, 2026, covering plan-year 2025 claims. This is the newest plan year CMS has published: there is no Transparency in Coverage file for a plan year after 2027. The dataset list is at data.healthcare.gov . A test in this site’s build fetches that list on every run and fails if CMS publishes a plan year we have not acknowledged here. Every earlier release, plan-year 2024, plan-year 2025, plan-year 2026, is kept alongside it so the record is visible rather than a single year’s snapshot; /about says what changed between them. From the plan-year 2024 release to the plan-year 2026 release, external reviews filed went from 2,336 to 5,881. Overturned reviews went from 32.8% in the plan-year 2026 release to 22.2% in plan-year 2027, or from 32.6% to 32.6% without SelectHealth. We do not compare filed or overturned counts across plan-years 2026 and 2027. Some issuers may have counted pre-service appeals in their 2026 cells.

## Where these numbers come from

Where these numbers come from Counts: CMS Transparency in Coverage Public Use File (PY2027 release, PY2025 claims), data.healthcare.gov — US Government public domain . Rights and timeframes: 29 CFR 2560.503-1 (180 days, and your free right to the claim file) and 45 CFR 147.136 (4 months, and what qualifies), explained at HealthCare.gov . Expedited review is decided in about 72 hours under both sections. Reading either regulation from a script rather than a browser: eCFR answers automated fetches with a challenge page, so the same two sections are mirrored as government PDFs at govinfo.gov (29 CFR 2560.503-1) and govinfo.gov (45 CFR 147.136) .
